     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Turning now to the drawings and more particularly to FIG. 1, an illustrative embodiment of a pliers-like hand tool 10 of the invention is shown comprising first 12 and second 14 lever members which cross over each other at a pivotal connection. The first 12 and second 14 lever members comprise first 16 and second 18 handles connecting first 20 and second 22 jaws, respectively, through a pivot pin or shaft 24 defined by a bolt and a nut. By squeezing handles 16 and 18 together jaws 20 and 22 move toward each other from an open position of FIG. 1 to a closed attaching position of FIG. 3. 
     The lever members 12 and 14 are preferably of the type manufactured under the trademark &#34;Channel Lock&#34; by Champion DeArment Tool Co., in Meadville, Pa. and described in issued U.S. Pat. Nos. 2,592,927 and 2,640,381. 
     The first jaw is in the form of a U-shaped flat horizontal bifurcated lower jaw 20 having a pair of mirror image prongs 26 joined by a bight portion 27 defining a central rectangular-shaped notch 28 therebetween. It will be noted that an elongated through slot 29 is formed in run portion 30 of the upper jaw 22 to enable the pivot pin 24 to slide in the slot 29. The run portion 30 is formed with a set of matching arcuate grooves 31. The upper four grooves 31 have their entrances blocked-off by means of weld portions 31&#39; at leading edge 31&#34;. A lowermost arcuate groove 32 is not blocked-off by a weld portion thus allowing a complementary raised arcuate ribor key 32&#39; formed on the inner surface of lever arm 12 to be received in arcuate groove 32. This allows the pliers-like hand tool 10 to open to a single maximum setting shown in FIG. 2 and close to its FIG. 3 position. 
     FIG. 1 shows each of the prongs 26 formed with an arcuate concave depression 33. It will be noted in FIG. 5 that the mirror image arcuate depressions 33 each have their center of curvature aligned on transverse axis &#34;A&#34; of FIG. 7. The principal axis of cable conduit portions of a conduit fitting, to be described below, are adapted for alignment on the axis &#34;A&#34;. 
     The lower jaw 20 is depicted in spaced relationship to a vehicle cable shifter assembly generally indicated at 40. Only the forward portion of the gearshift mechanism sheet metal base 42 is shown wherein its front end is formed with a pair of vertically disposed cable mounting flanges 44 and 46 each bent upwardly from the base 42. The flanges 44 and 46 each have respective horizontally disposed open-ended slots 48 and 50 provided therein. Each of the slots 48 and 50 are adapted to receive a metal cylindrical tubular conduit fitting 52 including. The fitting 52 comprises a rearwardly projecting conduit portion 54 and a forwardly projecting conduit portion 56, aligned on a common principal axis thereof, supporting a cable core 58 within forward and aft projecting cable support tubes 60 as seen in FIG. 5. 
     Referring to FIG. 8 numeral 70 illustrates a spring steel retainer clip 70 for which the hand tool of the present invention was specifically designed. The clip 70 is generally U-shaped comprising a generally planar base 72 formed with a central slotted half-round opening 74 having a center of curvature 75. The clip 70 is symmetrical about a plane of symmetry that includes construction line defining a pair of mirror image spaced apart yieldable legs 78 lying in substantially the same plane and adapted to move toward and away from each other edgewisely. The legs 78 terminate in respective right-angled foot portions 79. Each leg 78 has a convex curved lead-in edge 80 defining entrance locking gap 82. The base 72 upper portion is formed with a transverse arcuate stiffening corrugation 84 and terminates in forwardly bent rib 86 having a free linear edge 87. 
     With reference to FIGS. 2 and 4 it will be seen that the clip 70 is initially inserted on the cable conduit fitting 52 with its legs 78 straddling the fitting. FIG. 4 shows a clip receiving annular notch 83, defined intermediate aft face 87&#39; of the shifter base attachment flange 44 and the opposed face of aft raised washer 88, formed on aft conduit portion 56. The clip 70 is adapted to be temporarily retained on annular notch 83 in a press fit manner by means of the clips converging lead-in edges 80. It will be noted that the forward conduit portion 54 is formed with a forward raised washer 89. With the forward raised washer 89 in flush contact with the forward face of the base attachment flange 44 the aft raised washer 83 is correctly spaced a predetermined axial distance from the flange aft face 87 to establish the axial location of notch 83 for receiving the clip 70. 
     Upon the hand tool 10 being fully opened in FIG. 2 it is moved laterally such that the lower jaw central notch 30 is positioned to receive the shifter flange 44 therein wherein the pair of prongs 26 straddle the flange 44. The prongs 26 are positioned such that each of their aligned arcuate depressions 32 are brought into nested relation with an associated fore and aft cylindrical projecting portion 54 and 56 of the conduit fitting 52. It will be noted in FIGS. 5 and 6 that the upper jaw 22 is formed with a vertically disposed die member 90 having a right-angled cut-out defining a horizontal shoulder portion 92 and a coextensive vertical flank portion 94. 
     With reference to FIG. 4 it will be seen that upon initial closing of the hand tool 10 the die portion 90 is moved downwardly such that the shoulder 92 is placed in flush contact with the clip rib 86 such that its free edge 87 abuts the flank portion 94 as seen in FIG. 4. With the clip 70 captured between the reward face of the support flange 44 and the raised washer 88 closing of the pliers-like hand tool 10 causes the clip to be forced downwardly. The closing force causes the legs 78 to spring apart and enlarge the gap 82 whereby the clip moves downwardly allowing the central opening 74 to fit around the cable attaching cylindrical portion 54 between the raised washer 88 and the support flange 44. 
     While the principles of the invention in connection with the specific apparatus has been described, it is to be understood that the foregoing detailed description has been made by way of example only and not as a limitation to the scope of the invention as set forth in the accompanying claims.
